• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky dang tay hoi. lieu va cac duc tang hanh vinh ((((cuu tre) OR (cua tre))) OR (cau tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac ky dang tay hoi. lieu va cac duc tang hanh vinh ((((cuu tre) OR (cua tre))) or (cau tren))*".
